Before you buy
A deep sump pan adds oil volume to the transmission, which helps when the fluid is hot or the vehicle works hard on grades and in rough terrain. The extra capacity changes the fill amount, so the fluid level should be checked carefully after the first fill and again after a few drives.
Pan depth also affects ground clearance and the space around the crossmember, driveshaft and exhaust. Measure the area before ordering, and make sure the pan seal sits flat on the case so the gasket does not pinch during installation.
- Check the fill level with the transmission at operating temperature, following your transmission’s procedure
- Inspect the crossmember and skid plate for clearance
- Replace the pan gasket or seal if the old one is damaged
- Look for metal flakes on the magnet after the first service interval
